Sully County, South Dakota

Sully County lies in central South Dakota. The Missouri River and Lake Oahe form its western border. Both are a big draw for fishermen.
The entire county is sparsely populated. Onida, the county seat, is the largest town. And it’s not very big. But what it lacks in size, it makes up for in character.
Agriculture drives the economy here. Wheat, corn, and sunflowers are common crops. The landscape is mostly flat. But it’s not boring. Sunsets here are spectacular.
